21 - 4x = 108

Subtract 21 from both sides

-4x = 87

Divide both sides by -4

x = -21.75

2. option d

Step-by-step explanation:

1) Diameter = 8cm

Radius = 8/2 = 4cm

2) Diameter = 8cm

Radius = 4cm

$Volume = \frac{1}{3} \pi r^2h = \frac{1}{3} \pi 4^2 \times 15 = 16 \pi \times 5 = 80 \pi = 251.2cm^3$

Write 4,706 × 10 11 in standard notation

aleksandrvk [35]

I am guessing that is 1011? Just to be safe, I will do 4706*10 and 4706*1011.

4706*10: So, 4,706 times 10 is 47060

4706*1011: 4,706 times 1011 is 4757766

Standard notation is the normal way of writing numbers. So the answers I wrote are all in Standard notation.

Kala purchased a prepaid phone card for $15. Long distance calls cost $12 a minute using this card. Kala Use her card only once

irina [24]

Kala call lasted for 0.36 minutes

Solution:

Given that Kala purchased a prepaid phone card for $15

Long distance calls cost $12 a minute using this card.

If the remaining credit on her card is $10.68

To find: Number of minutes her call lasted

Let "x" be the number of minutes her call lasted

Cost of 1 minute = $ 12

Total balance = $15

Remaining balance = $ 10.68

So we can frame a equation as:

Total balance = Remaining balance + Cost of 1 minute x number of minutes her call lasted

$15 = 10.68 + 12 \times x\\\\15 - 10.68 = 12x\\\\4.32 = 12x\\\\x = 0.36$

So her call lasted for 0.36 minutes
